Grade 5 UNS R56400 Titanium Alloy Bars

Grade 5 UNS R56400 Titanium alloy bars, corresponding to the Unified Numbering System (UNS) designation R56400, is a medium-strength, heat-treatable α+β dual-phase titanium alloy. It accounts for approximately 50% of global titanium alloy applications and is currently the most widely used titanium alloy material​

. The domestic and international standard designations for this alloy are clearly defined: it is designated as Grade 5 according to American Society for Testing and Materials (ASTM) standards, Ti-6Al-4V according to International Organization for Standardization (ISO) standards, and 3.7165 according to European standards.

As the "workhorse" of the titanium alloy family, the performance advantages of Grade 5 titanium alloy bars stem from their well-balanced alloying element composition-aluminum is used to achieve solid solution strengthening of the matrix phase, vanadium improves the alloy's high-temperature formability, and, combined with precisely controlled impurity levels, this achieves an exceptional balance between high strength, lightweight properties, excellent corrosion resistance, good fatigue performance, and machinability​

. In terms of application scope, this alloy bar has gradually expanded from its original role as a primary structural material in the aerospace sector to include medical implants-which demand extremely high levels of safety and durability-as well as the chemical and offshore engineering sectors, where stringent corrosion resistance is required. It is currently one of the metal structural materials with the most mature overall performance and the richest application history in the global industrial sector​

Chemical Composition of Grade 5 UNS R56400 Titanium alloy bars :

At room temperature (20°C), the typical indicators of its physical properties and their significance for engineering applications are as follows:

Density:

It ranges from 4.42 to 4.43 g/cm³, which is approximately 55% of the density of traditional structural steel. This value is the cornerstone of the alloy's "high-strength, lightweight" properties-provided that strength specifications remain comparable, structural components manufactured from this alloy can theoretically be made approximately 45% lighter, making it a key material for lightweight design in industries such as aerospace and high-end automotive.

Melting Point:

1635–1675°C. This value is significantly higher than that of ordinary structural steel and aluminum alloys, meaning that this alloy can maintain stable mechanical properties in moderately high-temperature environments up to 400°C, and its upper temperature limit for application is far higher than that of lightweight materials such as aluminum alloys.

Specific heat capacity:

526 J/(kg·K). This value is slightly higher than that of ordinary structural steel but significantly lower than that of aluminum alloys, which allows the alloy to experience relatively more uniform temperature changes when operating in high-temperature environments, thereby reducing the risk of structural deformation caused by uneven thermal stress distribution.

Modulus of elasticity:

114 GPa. This value is approximately half that of conventional structural steel, making it one of the titanium alloys with the highest modulus of elasticity among those currently in common use.

Phase Transition Point:

The temperature range for the transformation of this alloy's α+β dual-phase microstructure to a β single-phase microstructure is 980°C to 1010°C.
